Hi guys !

Since mpeg files tend to take up a lot of space in comparison to avi that's why I compress a lot from mpeg to avi. But sometimes there is a problem; while I load mpeg file into virtual dub I've got the following error: MPEG import filter : unexpected end of file. Can anything be done about this ??!!
Pls help.jantheraven@interia.pl

are you sure its MPEG1 ? Vdub cant read MPEG2, and the extension of the file wont tell you, its all .mpg

Check the pop up extended options in the open video file menu and then check the box for about partial mpg files. That tends to happen on incompleate dl of mpg files of corrupted files.

I've seen this, it's probably caused by file truncation or an encoding error. The input parser gets to the end of file before reading an MPEG end code. My guess is either one or both of the sequence_end_code 000001B7 hex or the System_end_code 000001B9 hex is missing. I usually open the file from AVISynth or use Tmpgenc/VFAPI to create an AVI that can be imported into Virtualdub.

If your a real masochist, you could try to reconstruct the file using a Hex editor. ohmy.gif

Hello again :-)

Thx for helping me with the problem. First I'd like to reply to ChristianHJW's answer: To be honest I don't know for sure if it's MPEG1 or MPEG2 (nor do I care) all I know is that the file extension is either *.mpg or *.mpeg.
I'd like to thank rolleyes.gif Tut_Ank rolleyes.gif for the hint :'pop up extended options in the open video file menu'. Yes it did work !!! Thx again.
With regard to SynchronousArts' answer; no, I'm not a masochist biggrin.gif & I'll try to stay that way but thx for contributing, anyways.

You should ! As i said, Vdub can only open MPEG1 video streams by default, not MPEG2.

You would get a different error if you try to open a MPEG2 file in VDub. The problem really must be bad encoding or only partial download.
